SLEEVE-WHIRL SPINDLE FOR SPINNING-FRAMES.

SPECIFICATION forming part of Letters Patent No. 333,822, dated January5,1886.

Application led April 21, 1884. Serial No. 128,744. (No model.)

To all whom, it may concern:

Beit known that I, EDWARD E. BRADLEY, of Stonington, county of NewLondon, State of Connecticut, have invented an Improvement in SleeveWhirl Spindles for Spinning- Frames, of which the following description,in connection with the accompanying drawings, is a specification, likeletters on the drawings representing like parts.

The object of my invention is to obviate evils due to too tight bandingor strain of the bands, and at the same time drive the bobbincarryingspindle frictionally or adhesively.

In my invention the spindle is divided or made in two parts,one partplaced in abolstercase and having a sleeve-whirl attached to it,beingherein called the whirl l or driving7 spindle, while the otherpart, which receives the bobbin upon is called the bobbincarry ing7 ordriven spindle, the latter having attached to it a supporting-foot,whichis held frictionally or adhesively to apart of the sleevewhirl of thespindle, as will be described.

Figure l represents a spindle and its co-operating parts to bedescribed, the former iu elevation and the latter in vertical section;Fig. 2, alike view of a modification, and Fig. 3 a section of Fig. 2 inthe dotted line x x.

In the drawings, A represents a spindlerail, and B a bolster case andstep of usual construction, it having a suitable bolster or bushing, C,which in practice will be grooved in any usual manner for the passageand circulation of oil. The rotatable whirl-spindle D, having its lowerend entered loosely into the stationary bolster-case, has securelyattachedto itthesleeve-whirlD,iianged,asusual, for the reception of thespindle-'driving band, and, as herein shown, the said sleeve-whirl isprovided with a cap, E, having a lip or projection, 2, to support oneend of a spring, s, the opposite end of the said spring resting againstthe spring-support g2, attached to and moving in unison with the drivenspindle G, the latter having attached toit the supporting foot orportion g3.

In Fig. l the supporting-foot g3 and springsupport g2 are connected by asleevelike portion, which is extended downward about the tubular body ofthe sleeve-whirl and between it and the cap E, the spring s placedinside the cap and resting on the lip g2 serving to hold the drivenspindle G down with its supporting-foot g3 against a washer, m, on thesleeve-whirl, thus rotating the driven spindle G through the frictionexerted by the spring s, the force of which may be varied and made moreor less by adjusting the cap E, screwthreaded, as shown in Fig. 1, andengaging a threaded part of the projection h of the sleevewhirl. A smallspace, 3, in practice about one one-hundredth of an inch, is leftbetween the sleeve-whirl and the supportingfoot g3,to permit the spindleG to adjust or center itself to its load, as is well understood, thesupportingfoot g3 being held against the washer m by the stress of thespring s, as stated.

In the modification shown in Fig. 2 the cap E is attached to the upperend of the sleevewhirl, and the lip g2 for supporting one endof 70 thespring s is made as a collar screwed upon the driven spindle,a portionof which is passed into the cap E, the portion 2 of which acts againstthe opposite end of the said spring.

In both the spindles described the principle of operation is the same.

I am aware that a bobbiucarrying spindle has been driven from asleeve-whirl or lower spindle by means of a projection on one entering anotch in the other, thus forming a positive driving means; but I am notaware that one part of a spindle has been made to drive the other parti'rictionally through the intervention of a spring, and especially aspring the force of which may be adjusted.

I have shown but do not herein broadly claim the downwardly extendedsleeve attached to the bobbin-carrying or driven spindle G; neither do Iclaim its combination, broadly, with the sleeve of the whirl, as thatforms the subject of claims in my application No. 128,745.

I claim- 1. The rotatable whirl-spindle D, the stationary bolsteccaseprovided with a chamber to receive the lower end of thewhirl-spindle,the whirl attached to the said spindle,the cap providedwith the iiange 2 and a washer, combined with the spring s and thebobbin-car rying spindle` provided with a supporting-foot, g3, and alip, g2, the said spring acted upon or held between the said flange andlip holding IOO the foot y3 against the washer and permitting l force ofthe springend with a support for the ro the bobbin-carrying spindle tomove or tip I said spindle D, substantially as described. laterally onor with relation to the Whirl- In testimony whereof I have signed myspindle, the combination being and operating name to this specificationin the presence of substantially as described. two subscribingWitnesses.

2. The bobbin-carrying spindle provided EDWARD E. BRADLEY. with a footand spring support and the spring, lVitnesses: combined with thewhir1-spind1e D, provided Jos. F. JOSEPH,

With a Whirl and adjustable cap, to vary the WM. A. GILBERT.
